Abstract : The Combat Sample Generator (COSAGE) was constructed so that a number of synergistic effects relating to the joint action of combat arms could be simulated within the same -mode-1. For example, direct support artillery supporting armor and infantry in battle could not be simulated prior to the introduction of COSAGE. The same is true for the COSAGE simulation of Army aviation, engineers, and USAF functions. Throughout the past decade, COSAGE has been used to support requirement studies such as those involving the need to determine ammunition requirements for near-term and outyear scenarios. COSAGE has also been employed in capability studies and in quick reaction, real-time direct support for such operations as DESERT SHIELD and DESERT STORM.
